LS08-30 Valve

SYMBOL:
LS08-30 Valve symbol

DESCRIPTION
A load-shuttling, screw-in, cartridge-style, hydraulic check valve for use in
blocking circuits where a priority of flow/direction is given to a higher pressure
circuit over a lower one.

OPERATION
The LS08-30 will allow flow from the higher pressure of 1 or 3 port to the 2 port.
The valve is commonly used to direct oil from the pressure side of a bidirectional
hydraulic motor to a pressure-released hydraulic brake.

FEATURES
• Rapid response to load direction changes.
• Compact size.
